Overview and Advantages of ELBEELSO Hydraulic Lift in Weinan Factory of Shaanxi Province on February 18, 2019

ELBE ELSO液压升降机由行走机构,液压机构,电动控制机构,支撑机构组成的一种升降机设备液压阀是自动降低管路工作压力的专门装置,用于气动回路中,对压缩空气的压力值进行调节,使设定的压力值近于恒定在没有先导信号输入时,处于常闭状态变量液压泵的释放控制手柄,斜盘会自动退回中位。流量变为零当先导气路的压缩空气进入B腔后,液压减开始工作农机液压泵机械操纵、液压伺服排量控制可以保持斜盘的角度以及相应的排量液压油由叶片泵形成一定的压力,经滤油器、隔爆型电磁换向阀、节流阀、液控单向阀、平衡阀进入液缸下端,使液缸的活塞向上运动。


ELBE ELSO Hydraulic Lift is composed of walking mechanism, hydraulic mechanism, electric control mechanism and support mechanism. The hydraulic valve of elevator equipment is a special device for automatically reducing the working pressure of pipeline. It is used in pneumatic circuit to adjust the pressure value of compressed air, so that the set pressure value is nearly constant when there is no pilot signal input, it is in constant closed state variable hydraulic pump. Release the control handle and the swashplate will automatically return to the middle. When the compressed air in the pilot air passage enters the B chamber, the mechanical control and hydraulic servo displacement control of the hydraulic pump of agricultural machinery can keep the angle of the inclined plate and the corresponding displacement of the hydraulic oil, which forms a certain pressure from the vane pump, enters the lower end of the cylinder through the oil filter, flameproof electromagnetic commutation valve, throttle valve, hydraulic control one-way valve and balance valve, so as to make the piston of the cylinder. Move up.

提升重物,ELBE ELSO其额定压力通过溢流阀进行调整,通过压力表观察压力表读数值液压泵良好的主轴油封,即使在低温环境壳体压力较高时也不会发生泄漏液缸的活塞向下运动。液压油经防爆型电磁换向阀进入液缸上端,液缸下端回油经平衡阀、液控单向阀、节流阀、隔爆型电磁换向阀回到油箱。为使重物下降平稳,制动安全可靠,在回油路上设置平衡阀,平衡回路、保持压力,使下降速度不受重物而变化,由节流阀调节流量,控制升降速度。为使制动安全可靠,防止意外,增加液控单向阀,即液压锁,保证在液压管线意外爆裂时能安全自锁。

The rated pressure of ELBE ELSO is adjusted by relief valve. The pressure gauge is used to observe the good spindle oil seal of numerical hydraulic pump. Even when the shell pressure is high in low temperature environment, the piston of leakage cylinder will not move downward. The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil returns to the tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic reversing valve. In order to make the weight drop smoothly and brake safely and reliably, a balance valve is set on the return road to balance the circuit and maintain the pressure, so that the descending speed is not changed by the weight. The throttle valve regulates the flow rate and controls the ascending and descending speed. In order to make the brake safe and reliable and prevent accidents, a hydraulic control one-way valve, i.e. hydraulic lock, is added to ensure the safety of self-locking when the hydraulic pipeline bursts unexpectedly.
